My cummins has green coolant since I bought it and from 2002 and older cummins are green coolant while Chrysler and cummins had changed from green coolant to HOAT after 2003.

I did compare the mopar ms7170 and ford motorcrafts green coolant while ford said it is meets or exceed the requirement of Chrysler ms7170.

Motorcrafts green is ethylene glycol-based.
